Trust Architecture 2.1 is built upon a foundation of hardware-enforced security boundaries. Rather than relying solely on software-based protections, which can be modified or bypassed, the silicon itself enforces the security state of the processor. 1. Internal Boot ROM (IBR)
Accelerates RSA (up to 4096-bit) and ECC signatures.
Once the software is verified in a non-fused state, you must permanently configure the device. Program the Public Key Hashes into OTP fuses. qoriq trust architecture 21 user guide
One-Time Programmable (OTP) fuses permanently store the device's root of trust. These fuses hold the SHA-256 hashes of the public root keys, security configuration flags, and the OEM secret symmetric keys used for decryption. 2. Secure Boot Flow and Chain of Trust
Configure the RCW (Reset Configuration Word) to enable secure boot mode. Trust Architecture 2
This guide provides an overview of the core components and implementation steps for developers working with TA 2.1 enabled processors. Core Security Pillars
The central hardware unit governing security policy enforcement. Internal Boot ROM (IBR) Accelerates RSA (up to
The QorIQ Trust Architecture 2.1 (TA 2.1) represents a sophisticated security framework designed by NXP to protect embedded systems throughout their entire lifecycle. Implementing this architecture ensures that your hardware remains a "Trusted Platform," capable of resisting unauthorized code execution, physical tampering, and data theft.
Protecting sensitive data and detecting physical intrusion.
Combine the signature and the image to create a secure image ready for deployment. Phase 3: Secure Boot Configuration
The SNVS is a dedicated security subsystem that remains powered (often via a coin-cell battery) even when the main processor is powered off. It manages:
